Abstract:

To resolve the color-register problem on web-press machine, a kind of networking register system was presented. Firstly, a special diamond mark was designed, which is easier to be embedded. Secondly, the high-speed cameras with external trigger signal were adopted to capture mark images under the control of synchronous encoder unit, at the same time the real-time deviation of color was obtained by analyzing the mark image. Lastly, the data of color deviation were transmitted to the press system over Ethernet. Thus, a close-loop and real-time system was built. Especially, an Ethernet solution for the press machine with many towers was proposed. According to the actual customer’s reports, waste of newspaper decreases greatly, in addition, print quality and print efficiency are both promoted.
